What is claimed is:

1. In a railway car, a car bottom comprising a unitary casting including a central floor portion, side floor portions i-n a horizontal vplane above that -o the Vcentral floor portion and having Wheel hoods formed therein, and pedestals formed within and depending from the wheel hoods and each provided with a substantially centrally arranged spring pocket.

2. In a railway car, a `body comprising ya .unitary cast metal bottom portion formed to provide central and side floor portions, wheel hoods formed with the yside iloor xportions and sloping downwardly toward the side edges of ,the latter and pedestals formed with the bottom portion at the lwheel hoods and each provided with aspring pocket.

3. In arailwa'y car, a 'body `including a unitary cast metal bottom portion comprising central and side floor `portions arranged respectively in Jdiierent horizontal planes, wheel 'hoods formed with the :side floor portions and sloping idownwardly'toward the Vside edges `of the latter, .and pedestals .formedwith the bottom jportion at the wheel hoods and each provi-ded with la `:spring Wheels, journal boxes in which the vend portions of the axles are arranged, a unitary -cast metal `car bottom having acentral oor portion vin a plane intersecting the upper -portion-of the wheels and side floorv portions in a plane above .the central floor portion and provided with unitary-'hoods covering the wheels, pedestals integral with the cast metal car bottom and varranged within and "depending from 'the `wheel hoods and in which the journal boxes yare arranged, spring pockets formed with the pedestals, and journal springs interposed between the journal boxes and the spring pockets.

6. In a mine car, wheels, axles carried by the wheels, journal boxes arranged outside the wheels and in which the end portions of the axles are arranged, and a mine car body comprising a unitary cast metal bottom portion having a central floor portion positioned between the Wheels and in a horizontal plane intersecting the upper portions of the wheels, and side floor portions in a horizontal plane above that of the central floor :portion but :which also intersects the upper portions of the wheels, said cast metal bottom portion including wheel hoods formed in the side floor portions vand covering the wheels, pedestals depending from the side edge portions of the car bottom within the wheel bodies and arranged outside the wheels and in which the journal boxes are arranged, spring pockets formed with the pedestals, and journal springs arranged in the spring -pocketsfand Vbearing againstthe journal boxes.

'7. In a mine car, wheels, axles -carried by the wheels,.journal boxes arranged outside the wheels and in which the Aend portions of the axles are arranged, a unitary cast metal car bottom having :a central `floor portion and side floor portions arranged in diierent horizontal planes but each plane intersecting the upper portion of the wheels, said side floorportionsibeing provided withinte- Igrally formed rhoods covering 'the wheels, pedestals Acast integral with the car kbottom and arranged Within the Wheel hoods adjacent the side edge :portions of the car vbottom, spring pockets formed with the pedestals, and journal springs interposed `between 'the journal boxes and the spring pockets.

'8. LIn`*a mine car., va body, 'wheels and axles supporting the same, said body being provided YWith a 'unitary cast metal bottom vhaving wheel Vhoods and spring pockets, the latter being Aarranged adjacent the side edge portions of fsaid bottom and being formed with said Wheel hoods,

said wheel -hoods sloping downwardly and out- Wardly toward 'the side edge p'ortionslof the bottom and having at least portions thereof above the spring pockets arranged at a ylevel below the highest parts of the Wheels.
